    Abstract: There are provided methods of scheduling a satellite manoeuvre comprising: receiving parameters for one or more planned manoeuvres to move the satellite (100) from a current orbit to a new orbit, wherein the parameters include a time and duration of each of the one or more planned manoeuvres; receiving times of eclipses of the Sun by the Earth during future orbits of the satellite; and scheduling the manoeuvre to take place according to the determined parameters and the times of eclipses.

    Abstract: A data acquisition system for a satellite (10) comprises at least one camera (2), a device for controlling ambient parameters and processing radiofrequency signals (3) and a microprocessor (4). The camera (2) can be activated so as to acquire images of the Earth's surface, generating optical signals representative of those images. The device for controlling ambient parameters and processing radiofrequency signals (3) is interfaceable with a first antenna (11 ) in order to receive radiofrequency signals and manage the ambient parameters/attitude of the satellite (10), and a second antenna (12) in order to receive radiofrequency signals interpreted by the microprocessor (4) so as to perform operations on the camera (2) or packet uplink/downlink operations.

    Abstract: A system for controlling an operation of a vehicle to rendezvous with a target over a finite time horizon, wherein the vehicle and the target form a multi- object celestial system. A processor to formulate passive unsafe regions as passive safety constraints. The passive unsafe regions represents regions of space around the target guaranteeing collision trajectories with the target, in an event of total thruster failure. Update a controller having a model of dynamics of the vehicle with received data, and subject the updated controller to the passive safety constraints to generate control commands that produce a collision free rendezvous trajectory which avoids unsafe regions for the specified time period, guaranteeing a collision free trajectory with respect to the target in the event of the total vehicle thruster failure, so the vehicle does not collide with the target. Output the control commands to activate or not activate thrusters of the vehicle.

    Abstract: A method for orbital collision screening comprising, obtaining trajectory information of a plurality of objects moving on predictable paths. For each one of the plurality of objects, based upon respective trajectory information of the one of the plurality of objects, computing, a respective spatial descriptor of the path of the one of the plurality of objects, and storing the respective spatial descriptors of each of the plurality of objects in a data structure. Subsequently obtaining trajectory information of a further object, and based upon the trajectory information of the further object, computing a spatial descriptor of the path of the further object. Making first comparisons of the spatial descriptor of the further object against the respective spatial descriptors of each of the plurality of objects stored in the data structure to determine whether each of these first comparisons indicates a possible collision risk. Based upon each of the first comparisons, if the first comparison indicates a possible collision risk, determining a result of a close approach determination between the respective trajectory information of the respective one of the plurality of objects and the trajectory information of the further object, and taking an action based on result of the close approach determination satisfying a predetermined threshold.
